Ipv6 Address Configuration Method in Wireless Mobile Netowrk and Apparatus Therefor

1. An address configuration method in which a router configures an Internet Protocol (IP) address of a terminal, the method comprising: extracting a media access control (MAC) address from a field of a MAC management message requesting an initial registration received from the terminal; generating an interface address of the terminal by using the MAC address; generating the IP address of the terminal by attaching a network prefix of the router to the interface address of the terminal; and transmitting the generated IP address to the terminal in a field of another MAC management message, wherein the generated IP address is transmitted to the terminal prior to the terminal performing an auto-configuration of its IP address, and wherein the transmitted IP address is used by the terminal for performing auto-configuration of its IP address, and wherein the other MAC management message is a provisioned dynamic service addition request (DSA_REQ) message and the field of the other MAC management message in which the generated IP address is transmitted to the terminal is a convergence sublayer (CS) parameter encoding rule_packet classification rule_IP masked destination address field among fields of the provisioned DSA_REQ message.

2. The method of claim 1 , wherein the generating of the interface address of the terminal comprises performing duplicate address detection (DAD) to verify uniqueness of the interface address of the terminal.

3. The method of claim 1 , further comprising, after transmitting the generated IP address to the terminal, receiving a provisioned dynamic service addition response (DSA_RSP) message from the terminal.

4. An address configuration method in which a terminal configures an Internet Protocol (IP) address of the terminal, the method comprising: transmitting a message to a router requesting initial registration, wherein the message includes a media access control (MAC) address of the terminal; extracting information used for auto-configuration of the IP address of the terminal from at least one message received from the router, wherein the information is generated by the router based on the MAC address of the terminal; performing auto-configuration of the IP address of the terminal by using the extracted information; and transmitting a resulting information message to the router, wherein the extracting of the information comprises: analyzing a field of a message accepting the initial registration received from the router and extracting a to-be-used IP address allocation scheme there from; and extracting from a field of a provisioned dynamic service addition request (DSA_REQ) message received from the router the IP address of the terminal, an IP address of the router, a duplicate address detection (DAD) result, and a network prefix.

5. The method of claim 4 , wherein the performing of the auto-configuration of the IP address of the terminal comprises: generating a router advertisement (RA) by using the IP address allocation scheme identified in the message accepting the initial registration received from the router; generating a neighbor discovery (ND) response and information on a network interface prefix used in IP version 6 (Ipv6) to match with a message format by using the IP address of the terminal, the IP address of the router, the DAD result, and the network prefix; and transmitting the generated RA, ND response, and information on the network interface prefix to an IP protocol layer of the terminal.

6. An Internet Protocol (IP) address configuration apparatus for a router, the apparatus comprising: a terminal media access control (MAC) address extractor for extracting a MAC address of a terminal from a field of a MAC management message requesting an initial registration of the terminal; a terminal network address generator for generating an interface address of the terminal based on the extracted MAC address of the terminal; and a message generator for generating another MAC management message including an IP address of the terminal that is configured based on the interface address of the terminal and a network prefix of the router, and for transmitting the other MAC management message to the terminal, wherein the other MAC management message including the IP address of the terminal is transmitted to the terminal prior to the terminal performing an auto-configuration of its IP address, and wherein the IP address of the terminal is used by the terminal for performing auto-configuration of its IP address, and wherein the other MAC management message is a provisioned dynamic service addition request (DSA_REQ) message and a field of the provisioned DSA_REQ message in which the IP address of the terminal is included is a convergence sublayer (CS) parameter encoding rule_packet classification rule_IP masked destination address field among fields of the provisioned DSA_REQ message.

7. The apparatus of claim 6 , further comprising a duplicate address detection (DAD) unit for verifying uniqueness of the generated interface address of the terminal.

8. The apparatus of claim 7 , wherein a result of the DAD is transmitted to the terminal using an available field of the provisioned DSA_REQ message.

9. The apparatus of claim 6 , wherein the IP address of the terminal is generated by attaching the network prefix to the interface address of the terminal.

10. The apparatus of claim 6 , wherein the message generator attaches the IP address of the terminal, an IP address of the router, a result of a duplicate address detection (DAD), and the network prefix to one or more available fields of the provisioned DSA_REQ message.

11. An Internet Protocol (IP) address configuration apparatus for a terminal, the apparatus comprising: a transmitting/receiving processing unit for processing transmitting/receiving messages between the terminal and a router; a message analyzer for attaching a media access control (MAC) address to a message requesting initial access that is transmitted to the router, and for extracting information used for auto-configuration of an IP address of the terminal from at least one message received from the router, wherein the information is generated by the router based on the MAC address of the terminal; an address auto-configuration agent for acquiring the IP address of the terminal based on the extracted information; and a message generator for generating a message to notify the router that the terminal has completed auto-configuration of the IP address of the terminal, wherein the address auto-configuration agent analyzes a field of a message accepting the initial registration received from the router and extracts a to-be-used IP address allocation scheme there from, and extracts from a field of a provisioned dynamic service addition request (DSA_REQ) message received from the router the IP address of the terminal, an IP address of the router, a duplicate address detection (DAD) result, and a network prefix.

12. The apparatus of claim 11 , wherein the address auto-configuration agent generates a router advertisement (RA) by using the IP address allocation scheme identified in the message accepting the initial registration received from the router, and transmits the RA to an IP protocol layer of the terminal.

13. The apparatus of claim 11 , wherein the address auto-configuration agent generates a neighbor discovery (ND) response and information on a network interface prefix used in IP version 6 (Ipv6) to match with a message format based on the extracted information, and transmits the ND to an IP protocol layer of the terminal.
